LAMP'.

To all whom it may concern:

Be it known that I, VM. P. PATTON, of the city of Harrisburg, county ofDauphin, and State of Pennsylvania, have invented certain new and usefulImprovements in Hand and Stand Lamps; and l do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, and to the characters ofreference marked thereon.

The nature of my invention consists in constructing and arranging theseveral parts of this lamp in the manner hereinafter set forth.

In the annexed drawings making a part of this specification (13,)represents a cylindrical cage or jacket made of brass or other suitablemetal having four apertures c, c, c, c, in its side so placed inrelation to each other as to allow the four equal upright sections 8, 8,S, 8, to remain. Two of these sections that are opposite to each otherare slotted vertically for the accommodation `of the guide pins z', z',(said pins are fastened rigidly upon the outside of the upper orcylindrical portion of the perforated air chamber (0,) to be hereinafterdescribed). The said sections of metal in jacket (B,) also serve toconnect the upper and lower parts of said jacket together. The upperpart, from where the sections join it, is a cylinder having its upperedge scalloped.` 0n its inside surface immediately above the apertures,c, c, c, c, is placed the deiiector (c) which is raised spherically inthe center, having a iiange (K) by which it is fastened to the jacketThe spherical or raised part is slotted to correspond with the wick tubesaid slot is made somewhat longer and wider than the tube, the flange(K) has perforations in it to aid drafts. Said deflector is fastenedrigidly in its place, and serves to support the chimney (A) which ismade in the usual form, having a flange pro jecting from its lower end,thus forming a base on which it rests, and by which it is held in closeconnection with the lamp. The device by `which this is accomplishedconsists of the peculiarly shaped springs, lW, `W. These are constructedof one piece of metal. I do not desire to confine myself to suchconstruction, as the springs may be made separate, and fastened in themanner as described, and thus embody the same principle or method ofaction that is found in my device as above described (Fig, 2) .and arefastened upon the inside ofthe upper seal loped .edge of jacket (B) at apointequi.-

distant from the ends or toes w, w. `The 'deflecton thus leaving a spacebetween the' back of the toes andthe scalloped edge of jacket The object of this construction is to allow the springs to have a lateral aswell as verticalmotion, and thus accommodate themselves to any variationin thickness as well as diameter (from edge to edge) of the flange on``chimney (A). They are aided in theiroperation bythe screw (t,) which isso placed in the upper scalloped edge of jacket (B) as to be equallydistant from the said toes.

The lower part of jacketw(B) is made similar to the upper part, withexception of the annular swage (a), which encircles it just where thesections 8, 8, `8, 8, join the said part. The swage is so formed as toproduce an annular recess on the inside of the jacket, corresponding to`the swell or bead upon the outside. The vertical slots in two of thesections 8, S, run into or communicate with this recess for the purposeof allowing the guide pins i, al, to traverse the same when required.The perforated air chamber (C) is made in the form of an invertedfrnstum of a cone, terminating in a cylinder at its upper or largeredge, and a screw at its lower or smaller end. The cylindrical portionis scalloped to correspond with the four apertures c, c, c, c, in jacketthe said cylindrical portion of the air chamber is made of such size inrelation to the jacket as to allow it to pass neatly inside of the same,were it not for the pins z', z', which project from the cylindrical partof airchamber (C) at opposite points. i

Two slots 7, 7, are made from the lower edge of jacket `into the swageto admit the pins z', z', into the samethese slots are made a little ontof line of the vertical slots in sections S, S, but directly oppositeeach other to correspond with said pins, so that by making the pins toenter these slots till they reach the swage, then turning` the jacket(B) to bring the said pins in line with thevertical slots, the case orjacket (B) may be placed in proper position upon the air chamber Theconical part of air chamber (C) is perforated throughout its entiresurface with small holes to admit air, it also supports the wick tube,f, which is fastened at its lower end to the same, said tube is made inthe form usually seen in lamps of this class (carbon or petroleum oil)and has the wick elevator attached to its side, said elevator consistsof two serrated wheels placed upon the same shaft and communicating withthe wick through two slots made in the tube for that purpose, said shaftprojectsthrough one side of the air chamber (C) and is provided with athumb wheel (g) to elevate or depress the wick as may be desired.

The screw upon the base of the air chamber (C) has its nut in the part(D) which is f fastened rigidly upon the body (F) of the lamp, said partor nut is made in the manner usual to lamps of this class with eXceptionof the teat or projection (2) this teat has a bearing upon the upperedge of the sleeve (B) which encircles the nut (D) said sleeveterminates at its base in a petticoat or oo ncave flange (E) `Its upperedge is made so that part is parallel with the base line, the other partrising on an incline (to the base line) and then descending in the samemanner till it joins the parallel part. Thus forming a cam to operateagainst the projection (2) upon the nut (D) so that when operated uponby turning to the right or left it forces the concave flange orpetticoat (E) in close connection with the outside of the oil receptacle(F). The said petticoat (E) is made t0 conform exactly in shape with theupper portion of the body of the oil chamber. Said chamber (F) isintended to be made spherical (or approaching it) in shape and isperforated in its upper portion with a round hole (6) of sufficient sizeto permit the pouring of oil through it into the lamp readily. There arefour holes S, S, S, S, made in the petticoat (E) of an equal size withthe one `in the oil chamber, and equidistant from each other. Said holesare also placed in such relation to the incline on the upper edge of thesleeve (R) that one of them shall come opposite the aperture in the oilvessel when the incline is made to recede from the projection (2) on nut(D), and in like manner to recede from the said aperture when theincline is made to approach and force against the said teat orprojection. The said petticoat is lined or coated upon its inner surfacewith a thin gutta percha or leather gasket having perforations in it tocorrespond with those in the petticoat, said gasket serves to produce aperfectly secure joint between the petticoat and oil chamber and thuseifectually to close the oil passage in the same when it is desired.

Having fully described the different parts in their regular order I willproceed with the operation of the same. i

First. It is clearly evident that when the operator desires to fill thelamp all that is necessary is to turn the petticoat so that the inclineon the upper edge of the sleeve Y Y (R) recedes from the projection (2)on nut (D); this will bring the aperture in the petticoat opposite theone in the oil chamber.

l/Vhen filled turning the same in the opposite direction carries theaperture in the petticoat away from the one in the oil chamber, and atthe same time the incline bearing against the projection forces thepetticoat firmly against the oil chamber thus perfectly closing the oilpassage and accomplishing the same instantly.

Second. When the operator desires to light the lamp he simplyelevatesthe jacket (B) f pins enter the swage this will carry the pins into theswage and thus secure it in this position. lVhen the lamp is lighted, byreversing the operation the delector and chimney are brought to theirproper position. i

Having thus fully described the construction and operation of myimproved lamp,

and pointed out its utility, what I claim-as new of my design andinvention and desire to secure by Letters Patent is- 1. The employmentof the adjustable and movable chimney support B, when it is constructedand arranged in the manner herein specified. Y

2. The combination of the support B, as

constructed, with the air chamber C, the two Y being arranged and usedin the manner set forth.

8. The construction and application of the Y petticoat or its equivalentsubstantially in the manner and for the purpose set forth Y anddescribed.
